The invention provides a method for increasing the viscosity of glycerol. The method comprises the step of dissolving a water-soluble polymer in glycerol. The invention also provides the use of the water-soluble polymer for increasing the viscosity of glycerol, and the use of the water-soluble polymer and glycerol for preparing polymeric microspheres. According to the invention, the water-soluble polymer is dissolved in the glycerol to improve the viscosity of the glycerol. By adding a very small amount of water-soluble polymer, the viscosity of glycerol is obviously improved. Furthermore, the water-soluble polymer and the glycerol are used in the preparation of the polymer microspheres, so that liquid drops in the emulsion are not easy to polymerize, the liquid drop fusion phenomenon in a mixed solution caused by insufficient viscosity of the glycerol is solved, and the application of the polymer microspheres in the field of microsphere preparation is greatly enlarged. 本发明提供一种增加甘油粘度的方法，所述方法包括将水溶性聚合物溶于甘油。本发明还
